ALBERT DREWITZ,OF SYRACUSE, NEW YORK.

RECEP'IACLE-CLOSURE.

To all whom it may concern Be it known that I, ALBERT Dnnwrrz, citizen of the United States, residing at Syracusc, in the county of Onondago and State of New York, have invented certain new and useful Improvements in Receptacle-Closm'es, of which the following is a specification, ref erence being had to the accompanying drawings.

This invention relates to improvements in receptacle closures and has for its primary object to produce a device of this character which is very simple in construction, may be i easily and quickly applied to the receptacle and provides what is in effect an air-tight or hermetical closure therefor.

My invention has for another object to provide a closure for cans, jars and similar vessels con'n'nonly used for preserving food stuffs embodying a plurality of relatively adjustable clamping arms mounted upon the top or cap for the vessel, and means on the can with which said arms cooperate where by an effective clamping action is secured, each of said arms being provided with a suitable clamping screw.

My invention has for a further object to produce a device of the above character which is highly efficient and reliable in practical use, capable of manufacture at small cost and may be easily and quickly applied to or removed from the jar or vessel.

\Vith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following de scription and accompanying drawings, in which Figure 1 is a side elevation of a can or jar provided with my improved closure; Fig. 2 is a top plan view thereof; Fig. 3 is a section taken on the line 3-3 of Fig. 2; Fig. 4 is a detail perspective view of one of the clamping members; Fig. 5 is a section similar to Fig. 8 illustrating a slightly modified form of the invention.

Referring in detail to the drawing, 5 designates a can or jar which is provided upon its upper edge with the usual annular head or flange indicated at 6.

In the preferred form of my invention, the top of the receptacle which is preferably Specification of Letters Patent.

constructed of the same material as the body thereof is centrally provided with an upstanding boss 7 in which a threaded rOd 8 is secured in any preferred manner.

9 designates a plurality of clamping arms which are all of the same form in construction. Each of these arms is provided in its inner end with a short longitudinal slot 10 which permits of the limited radial movement of said arms upon the bolt 8. The outer end of each of these clamping arms is angular-1y disposed as shown at 11 and provided with an inwardly extending terminal lug 12. The inner ends of the arms are adapted to be arranged upon the bolt 8 in superposed relation and a washer plate 13 is then disposed upon said bolt and a bowed leaf spring 14 disposed upon the top of this plate. A wing nut 15 is then threaded upon the bolt to bear upon the leaf spring and thus regulate the pressure of the ends of said spring upon the washer plate.

The under side of the top 7 of the receptacle is provided at its outer edge with an annular groove which is adapted to receive a packing strip of rubber, felt or other desired material, indicated at 16. When the top is arranged in position upon the open end of the vessel, the edge of the vessel wall is received in this groove and the packing strip rests thereon. This strip effectually excludes all air from the interior of the jar or other vessel. Each of the clamping arms 9 is provided adjacent its outer end with a screw 17 which has threaded engagement therein and is adapted for binding contact with the upper surface of the top 7 so as to force said top down and tightly engage the packing strip 16 upon the upper edge of the vessel wall. It will be obvious that by means of my improved construction of the closure and the arrangement of the clamping arms, the top or closure may be very easily and quickly applied to the jar or vessel to absolutely seal the same and exclude all moisture or air therefrom.

In Fig. 5 of the drawings, I have illustrated a slightly modified form. of my inventionwherein the can top 7 is centrally provided with a cylindrical disk 18 which is spaced from the upper surface of the cap and to this disk an annular ring 19 is secured at a number of points, said ring being disposed in spaced concentric relation to the outer edge of the disk. The clamping arms 9 are slightly different in form from those illustrated in the preferred embodiment of the invention, the inner ends of said arms being slightly curved upwardly as shown at 19*, for engagement with the under side of the ring 19. The clamping screws carried by the arms 9" are adapted for engagement with a separate ring or annulus 20 which is adapted to be arranged upon the upper surface of the top or closure 7. In this form, of the invention, I have shown the top as provided with a flange 7 to fit within the upper open end of the vessel to which the top is applied. It will however, be under stood that the particular construction of the; top itself forms no part of the invention, the same residing solely in the means forclamping said top in position on the jar.

From the foregoing, it is believed that the construction, manner of operation and several advantages of my invention will be? clearly and fully understood. The extreme simplicity of the device enables the operator to very easily and quickly apply the same to the upper open end of the can, jar or other; vessel. The device is extremely serviceable in practical use and by means of the same, the operator is relievedof considerable labor in hermetically sealing preserving jars and; other vessels or the like. It will be under stood that while I have above described the preferred construction and arrangement of the several elements employed, the invention is susceptible of considerable modification therein and I therefore reserve the right of} resorting to all such legitimate modifica; tions as may be fairly embodied within the spirit and scope of the appended claims.

Having thus described the invention, what is claimed is:

1. The combination with a receptacle top, of a plurality of relatively movable clamp-r ing arms adjustable radially with respect to; each other and circumferentially with respect to the receptacle top, means carried by the top upon which the inner ends of said arms are fulcrumed and adapted to oscillate, and a screw threaded in each of said arms and adapted for binding engagement with the top whereby said arms may be individually adjusted to engage the same with the receptacle and clamp the top in position upon the upper edge thereof,

2. The combination with a receptable top, of a threaded bolt centrally fixed thereto, a plurality of relatively adjustable clamping arms having limited radial movement upon said bolt, a nut threaded upon the bolt to retain the arms in. connection therewith, means yieldably holding said arms against vertical movement on said bolt, and a screw carried by each of the arms for binding engagement with said top to clamp the same upon the upper edge of areceptacle.

3. The combination with a receptacle top, of a threaded bolt centrally fixed thereto, a plurality of radially disposed clamping arms each provided in one end with an elongated slot for slidable engagement upon the bolt whereby the arms may be radially moved. to a limited extent, a washer plate arranged upon said bolt over the inner ends of said arms, a bowed leaf spring on said bolt bearing at its ends on said washer plate, a, nut

threaded upon the upper end of the bolt to regulate the pressure of said bowed spring, and a set screw carried by each of the clamping arms adapted for binding engagement upon the top to clamp the same upon the upper edge of a receptacle.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses.
